$7 Smart Component Tester (LCR-T4 M328)

[baja]

No, it will test components that are removed from the circuit. Sounds like it is a power supply problem. I'm guessing this clock uses 5VDC logic. You can either figure out what is wrong with the supply, or replace it with a AC mains to low volt supply brick. Does the printed wiring board have any silk screen legends that indicate voltage? I don't know what your electronic skills are.

They do make a model of this, that has a boost supply that can test Zener diodes to 30v. This is what I purchased last year off eBay (search for "LCR TC1", you can find a USA seller if desired).

Yeah, I remember from prior experience about removing the components to test them. I have minimum-t0-moderate electronic skills. There is no legend on it indicating voltage but I can remove it from the circuit and test the voltage and see what it is. The circuit board indicates it`s made in Hong Kong and has "0" jewels, lol. Thanks!
